Joe Jonas can’t get enough of new girlfriend Sophie Turner

Joe Jonas is “smitten” with his new girlfriend, “Game of Thrones” actress Sophie Turner — in part because “she has her own money,” we’re told.

“He loves her because she won’t let him pay for her all the time, which is so rare in girls he meets,” said a source. “She insists on paying her own way for flights when he asks her to come see him and offers to pay. Plus, he thinks she’s so smart and sexy.”

The source added, “He’s telling friends there’s something different with her, and he knew it as soon as they met.”
